Air Springs (Air Shock Absorbers)

ITT Enidine Inc. Air Springs are highly durable, precisely engineered and cost-effective for use in a wide variety of actuation and vibration isolation applications. With time-tested designs incorporating fabric-reinforced Wingprene or natural rubber flex-member construction and corrosion-protected end retainers, ITT Enidine Air Springs provide superior quality and performance. As actuators, Enidine Air Springs can provide either linear or angular motion.

These air springs (air shock absorbers) offer a favorable stroke-to-compressed-height ratio when compared to air cylinders, and they can accept a wide variety of actuation media such as air, water, nitrogen or anti-freeze. As isolators, ITT Enidine Air Springs are effective in reducing the harmful effects of vibration. They can simultaneously isolate vibration and regulate load height as well as allow for consistent vibration isolation under varying loads.

ITT Enidine Inc. offers a variety of air spring and air shock absorber types to meet your actuation or isolation needs. The Single, Double and Triple Convolute Bellows, Rolling Lobe and Sleeve Types are available in a wide range of sizes, with the end retainer style required to suit your specific installation.
